Lower back pain in combo with hip issues

I have struggled with sciatic nerve issues, L5 S1 area I have herniated disc. Over the past year I have recvd some steroid injections which have helped with the pain. Recently I was getting into bed, I kneed down to lift my body up and had this overwhelming excruciating pain in my hips area/ lower back it took my breathe away, I lunged forward facedown and after a few seconds the pain went away. I was able to go about what I was doing no issues.

This past week I was standing and going to sit in the drivers seat of my car and it happened again as I squatted down to sit between the steering wheel and the seat. It happened again same issue later in the day. It has now happened a few times more and it has really caught me off guard. Could this be something new ? Or could it all be related to the current issues I have going on?
